This cheap USB flash drive could double your MacBook Air’s storage

So, did you decide to save a little cash by getting the 128GB MacBook Air rather than the pricier 256GB version? Me too—and once I did, I learned the hard way how cramped a 128GB Air can get.

Nope, you can’t go to the Genius Bar and ask for a storage upgrade—the MacBook Air’s case is sealed too tight for that—but you can give it a big boost with a USB memory stick. This SanDisk Cruzer USB 2.0 memory stick (on sale for $23 on Amazon) boasts 128GB of storage, enough to double storage capacity of the bargain MacBook Air model. Need even more storage? There’s also a 256GB Cruzer stick for $53 (down from $70).
